Firstly, thank you for the quick response. There are a few things in your reply that I didn't understand however.
When you say "regulated product" what exactly does that mean?
And when you say "functionally the same" is there a guideline as to how different it can be? Using the example from my first post as an example, it serves the same purpose (ie shuting the unit down on an unsafe condition), however the processing unit is completely different with different internal logic, different termination strips, different power suply circutry etc.
Please bear in mind that I am neither an electrician or a lawyer, so I am not familiar with some of the terms etc.
Also, as we do not have any electricians at this particular branch of our company, we don't have an electrical code book. Is there somewhere a person could view an online version of the codes, for BC or Alberta?
Thanks again for any and all assistance on this.
